Title: Hot dip bath fumes removal and cleaning - using intermittent suction system and filter mat
Inventor: HOELTER HEINZ
IPC: C23C2/06
Filed: 1973-03-23

Title: Liquid crystal indicating cells - electrodes of stannic oxide contg antimony oxide improve crystal alignment
Inventor: SCHIEKEL MANFRED DIPL PHYS
IPC: G02F1/1337
Filed: 1973-05-09
Abstract: In order to make the electrodes, glass plates are coated with stannic oxide contg. 0.01-10 wt. % antimony oxide or bismuth oxide. A pref. method is to heat the glass plate to 560 degrees C and expose it to stannic chloride and alkali plus antimony trichloride in nitrogen as a carrier gas to obtain a deposit of SnO2 contg. antimony oxide. This coating is treated with photolacquer and etched to form the electrode, after which the plate is heated 1 hour at 500 degrees C. With this electrode, when no voltage exists across the cell, the liq. crystals are aligned homeotropically, i.e. the mol. length axes are oriented approximately perpendicular to the electrode surface. The cell is intended for use with liq. crystals which undergo reversible electro-elastic deformation when a driving voltage is applied.

Title: Sealing arrangement for transission system - has intermediate zone and sealing ring forming step like labyrinth seal
Inventor: RIEGER REINHARD
IPC: F16J15/40
Filed: 1973-08-03
Abstract: The device is for use where the transmission consists of a housing, an external shaft, an overrunning freewheel and an inner shaft. This type of transmission must have a seal for the bearing and freewheel lubricating oil. The use of radial and axial seals is not suitable for high rotational speeds. In this design, the housing has a circular raised zone projecting into a recessed portion of the outer shaft forming the intermediate zone. A sealing ring fixed to the inner shaft fits in this zone. The free end of the seal fits between the housing and the outer shaft. Axial sealing is provided by threading on the end of the seal.

IPC: G01P5/08
Filed: 1973-09-17
Abstract: The meter comprises two coaxial tubes of nonmagnetic or insulating material between which is located a series of coils to generate a magnetic field. The electrical potential established in the flow when a magnetic field is present is tapped by means of two electrode groups. One group is fixed to the outside of the outer tube and taps the potential corresponding to the fluid flow velocity and the other is fixed to the inside of the inner tube to tap the potential corresponding to the flow velocity through this tube.
Patent DE-2349893-A1 (DE)
Title: Spur gear profile with evolute shape - has two spherical contact surfaces one concave and other convex
Inventor: RIEGER REINHARD
IPC: F16H55/08
Filed: 1973-10-04
Abstract: The intention of the design is to reduce tooth interference thereby minimizing wear and loss of power. There is also an improved load capacity since a large proportion of the contact surface between the teeth is in fact in contact when throughout the period of load application. consequently a smaller gearwheel can be used with consequent reduction in weight and manufacturing cost. The spherical curvature of the teeth runs along the teeth and the radius of curvature on each face can be quite similar where there is a little play in the shaft and fine tolerances. Where there is play and the tolerances are larger a sharper curve is required on the convex surface than on the concave surface. The gear can be machined using normal machine tools.

Title: Winding device having contact driven package - with doffer which accelerates empty bobbin to working speed before changeover
Inventor: SCHIMINSKI HERBERT
IPC: B65H67/048
Filed: 1973-10-24
Abstract: Yarn is fed through a traverse guide and into a (pref.) helical guide groove of a driven roller with which a bobbin is in contact whereby the bobbin is rotated and the yarn is wound into a cross-wound package on the bobbin. When the package is completed an empty bobbin is moved into contact with the driven roller to accelerate it to its operating speed and an auxiliary yarn guide engages the yarn at one end of the field of movement of the traverse guide and forms it into a loop so that the yarn is moved out of the guide groove and is engaged in a retaining formation on the end of the empty bobbin whereby the yarn commences to wind on the empty bobbin. The auxiliary yarn guide pref. also moves the yarn to a cutter which severs the yarn between the two bobbins and pref. the two bobbins are mounted on a turn table such that as the dia. of the package on one bobbin increases the turntable rotation and moves the empty bobbin into contact with the driven roller. The doffing arrangement reduces to a minimum the loss of time and the yarn during changeover from a full to an empty bobbin.

Title: System to enter position of ship on sea chart - uses computer to determine position in terms of latitude and longitude
Inventor: KUNDLER WALTER
IPC: G01C21/22
Filed: 1973-12-20
Abstract: A projection system suspended above the chart table can project a position mark onto the chart and is pivotably mounted on gimbals along two axes.

The motors can be stepping motors which are controlled by a forward-reverse counter. The projector can have two division marks for reading off the zero position. There can be two position indicators to measure the angular position of the gimbal pins.

Title: Glass-pane-fitted door leaf or window frame - with slightly bent pane held flat under mechanical prestressing
Inventor: BAUM HANS DIPL PHYS DR
IPC: E06B3/58
Filed: 1974-03-21
Abstract: The door leaf or window frame is fitted with a glass pane, or a panel of transparent plastic, which is held inside a groove or pressed against battens. The pane or panel that is used is slightly bent originally, and bent back into a flat shape when inserted in the leaf or frame, by means of the glass-holding battens; here it remains under a mechanical bending prestressing, which acts so as to press it firmly against the battens. The pane may be a thermically prestressed safety glass pane, and it may be fitted with elastic cementing strip along the edges that are seated between the battens. There is no need for an elastic strip to hold the pane firmly in place.

Title: Harmful components measurement method - is especially of hydrocarbon concentration in water by means of flame ionisation
Inventor: RATFISCH WERNER ING GRAD
IPC: G01N33/18
Filed: 1974-05-16
Abstract: The tested liquid is admixed to the fuel gas feeding the flame. A measured-out dose of the liquid is fed into a stream of an inert gas. Liquid in the carrier gas is evaporated, and the mixture of carrier gas and vapour is fed into the fuel gas, and the hydrocarbon concentration electrically measured. Solid matter possibly deposited from the vapour is filted out. When water is analysed, evaporation is carried out at about 300 deg.C. The tested liquid is continuously circulated, and samples collected from its flow are fed into the carrier gas.

Title: Intermittent coupling bet. continuously driven input and output shafts - actuator causes spring force to connect input to output for pretermined part of revolution
Inventor: BAUER KARL
IPC: G04B11/00
Filed: 1974-08-02
Abstract: A coupling provides a time dependent intermittent connection between a continuously rotating input shaft and an output shaft. The input shaft (4) is rigidly connected to a crown gear wheel (7). A transmission gear wheel (9) is in mesh with an actuating pinion (20) and a pinion (18) coupled to the output shaft (16). The rear face of the transmission gear is in contact with a housing plate (12) that carries a formed strip spring (13), pinned at one end (13a). The spring projection is shaped (13b) to enter a recess (11) in the transmission gear without contact. In this condition the drive gear (7) and the transmission gear teeth (8) are disengaged. When the actuator gear is rotated through a few degrees the spring (13) force the teeth into mesh and the output is coupled with the slot (11) meets the spring again.

Title: Precisely guided printing wheel for counter - has intermediary bearings for the wheel acted upon by springs and centred on shaft
Inventor: VOSSELER MANFRED
IPC: B41J1/48
Filed: 1974-11-14
Abstract: In one design the type wheels (1) are individually spring-mounted and rotatable through the use of intermediary bearings (3) on a common shaft (2). The indexing mechanism comprises pinions (4) and toothed wheels (5) with printing type (6) which interact with the printing stamp (7) of the impression mechanism. The profile of the shaft is flattened (8) at one point and the intermediary bearing is guided laterally. A spring (9) on the shaft acts on the internal surface of the bearing and is compressed when the stamp strikes the type surface. This design ensures that the type wheels are guided smoothly.
